Where the magnetic plates are located, the vtrough is o en as indicated at 6, Fig; 2, and directly un 'er the plates are elect-roei'nagnets 7. Each vplate 'extends between the main partition andside Wall of thetrough and is of .the 'same length as* theopening. The

magnetic plates a'ieeach constructedhof a pieee 'of sheet iron or `other magnetic' metal which'has its longitudinal marginal- 'port-ions doubled under ,so thatv the plate willlbe-.ot'

two' thicknesses, beinv 'separated by aV sheet.. of peper, clot-li or' the 'ike '8,'as clearly shown in ig. 4. It has been `found' that with this arrangement the magnet-ic' attraction 4is more evenly distributed than when` asin'gle sheet of metalis used. The p olepi'eces 9110i' the' magnets are extended; transversely =of -2 the plates 5 so as to be approximately the same width as-the latter, andt-hese magnets may be of any' desired strength 'according tothe conditions V'of service.

Aan amalgamated plate 16 is removably7 fitteV ff *the electromagnets been operating a Suitable time, the amal a-v operations in the trough for testing pur oses, whereby itis possib e to determine w ether gold is escaping b being conducted olf the magnetic plates with the water. This amalgamated plate is used only occasionally in order to prevent loss of quicksilver. 'I he plate 16 rests on the bottom of the trough and has side walls"17. This amalgamated plate fits under the copperlining 1( and bottom strip 15, which are supported a Nay from the side Walls and bottom of the t' ough, respectively, so as to provide a recess or pocket 18 for receiving the upper end of the amalgamated plate or. testing device 16, there being a packmg strip 19 1n this recess lfor preventing wat@l rom leaking backwardlyunder the copper lining and strip and flowing through the openingt in the bottom-of the trough. The testing device or amalgamated plate may thus be securely held in place without requiring special fastenings.

In practice, the sluice trough is supplied with black sand in any suitable manner, which is carried -down by the Water through the passages formedv between yadjacent partitions,and`the outermost partitions and side walls of the trough. energized, will cause the magnetic particles to arrest the gold and the like which flows down the trough, the gold and particles to be separated moving alon the bottom of the trough beca-use 'of thelr being heavier than the magnetic particles, so that the lattligpwillv ent-rap the gold and the like on the .magnetic plates by thelines of force from After the trough has mated plate is inserted to make a test oi' gold losses. When' a loss of gold appears, the flow through the trough is 'stopped and the magnets denergized. The removable partitions are then taken out so as to permit the arrested particles on the magnetic plates to be scraped out ofthe trough. After the trough is cleaned, the partltions are replace-'d and the 'amalgamated plate removed so that another charge of metal particles to be separated Acan be supplied tothe trou h after thejmagnets are again ener ized, tie

previously described elng repeated.

` In Wiring the inagnets',1it is important' that the circuit connections with the magnetic poles' be such that those under one plate will'be all of the same polarity but diierent from the magnetic oles'under the other plate. That is to say,'1f the magnetic poles under one plate are posit-ive, those uner the 'other plate must be negative.

Vixen` there is not suilicient proportion of magnetic particles in the sandv to insure effective operation, iron filings or equivalent ymaterial can be mixed with the' metal bearing sand so that. precious metals canbe betw ter `separated.v y

From the foregoing description,'taken in connection with the accompanying drawings, the advanta es of the construction and of the method o o eration will be readil apparent to those skilled in the art to whic the invention appertains, and While I ave described the 'principle of operation o the invention, together with the device which ,l now consider to be the best embodiment thereof, I desire to have it'understood that the device shown is merely illustrative, and that such changes vmay be made when desired asare within the scope of the claims appended hereto.

Having thus described the invention, what I claim as new, and "desire to secure by Letters Patent, is

The combination of a trough, a magnetic plate arranged in the bottom thereof and consisting of sheet metal-of double thickness with a non-magnetic filling, and magnets arranged onthe plate.
